Intermittent A/C Issue - Please Help

Over the past year my A/C has been hit or miss..sometimes I can feel the cold air coming fine..and sometimes it will become just the fan...

Acura did a evacuation dye and recharge and found no leak...but I still notice the issue...

Odd is when I am accelerating..its as if the fan kicks in...when I am driving extremely slow or brake or come to a stop... the cold A/C kicks in intermittently..and sometimes goes back to fan air only...

Any ideas where I should look at next ? Apparently Acura checked the fuse as well

I'm lost

Sounds like you have some sort of restriction in your ac system. AC gauges showed show this.

Did you figure out what's wrong?
It seems like my 2012 TL starts to have a similar problem too..

Someone else had a pressure switch problem.

How about your internal temp sensors? Mine just came back with cleaned sensors and all is good.

Also, something to check .... My ex's Honda Odyssey (similar design) had some front end repair work done and the A/C didn't work right after. Finally I saw they forgot to plug in the temp sensor behind the front bumper. Plugged it in and everything worked just fine.

Could be a failing A/C relay, or it could be an issue with the pressure valve inside the A/C that allows cold low pressure refrigerant into the system and keeps the hot, high pressure stuff out.
